CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 278,843, dated June 5, 1883.

A pplioation filed October 2, 188-2. (No model.) i

wheels in which the wheel revolves around a fixed axle in conjunction with anti-friction bearing or guiding rollers placed within the body of the wheel, or, in other words, so as to produce a sun-and-planet motion and the ob jects of my improvements are to provide a means whereby the friction of the parts is reduced to a minimum, and the heating of the boxes and axles prevented, andlittle or no inbrication required. I attain these objects by the mechanism illustrated in the accompany ing drawings, in which Figure 1 is a sectional plan of my ear-wheel with one disk-plate removed. Fig. 2 is a vertical sectional elevation of the wheel. Fig. 3 is a plan view of one-half of the wheel-rim with one disk removed.

Similar letters refertosimila-r parts through out the several views.

The body, tire, and flange A of my wheel are eithercast whole or in two separate parts in central vertical sections, with the flange upon one-half of the rim, or the sections may be forged separately from good wrought-iron, and when so constructed separately the two parts are secured by square-shanked bolts, which may be of any convenient number.

To procure lightness, the webbing of the wheel may have a number of holes of any form made through the parts, while suitable central openings, B B, are formed in the web to receive the disk-plates, which form the hub or nave, to be hereinafter more fully described.

The hub is constructed in two parts, each the counterpart of the other, and formed of two disks or plates, D D, with inwardly-ex tending bosses with rounded bases, and flanges E at the outer edges of the disks, and when in position the inner face of one of these bosses is opposed to and rests against the face of the other or opposite one in close proximity, and a groove, F,- is formed around the hub, in which the inner edges of the friction or bearing rollers operate.

The frictional bearing rollers or wheels G are constructed of fiat pieces of metal, and are provided with rounded edges. They are placed in suitable numbers within and so as'to occupy the hollow space of the web of the wheel, and have suflicient room for play, but are not an ranged so closely as to bind one against the other.

In practice, when the wheel is cast or forged in sections, the parts are first bolted together, and the bearing wheels or rollers passed through the center or openings in the web and arranged in the manner shown in Fig. 1, when the two disk-plates.whieh form the'hub are placed in position in the openings at each side of the wheel, and the end of the axle H is forced into and through the openings in the center of the hub-plates by hydraulic or other power until the end ofthe axle is projected a sufficient distance beyond the face of the wheel in order to connect the trucks of the car or the car-axle box to the end of the axle, and this connection may be made in the usual way and with the ordinary boxing and hangers; but no lubricant will be required for the axle-box, as the axle does not revolve. if it should be deemed necessary, however, to key the hub to the axle, the axle may be forced through the inner hub of the inner disk-plate and keyed, when the other disk may be operated upon in like manner and keyed to the axle.

, Vhen the parts are in position it will be observed that the wheel is held loosely, or so as to have a little play between the two tlisk plates laterally, and that the periphery of the diskplates fits loosely into the circular openings in the web, so that sufficient room is had for the free action of the axle and hub without binding of the parts, while the flanges upon the outer edges of the disk-plate overlap the webs and limit the lateral play of the wheel, and, furthermore, that the supporting or friction wheels operate in the grooved hub between the disk-plates and the web of the wheel in a reverse manner to the trend of the wheel, with their upper bearings upon the inner face of the rim of the wheel and their lower bearing in the groove around the hub, in which position they are held between the dislcplates and the tire an annular recess, F, and the rollers G G, web of the wheel, and lateral orvertieal movearranged in said recess, all substantially as set ment or binding is prevented. forth.

Having thus described my invention, what I In testimonythat I claim the foregoing I have 5 claim, and desire to secure by Letters Patent hereunto set my hand and seal this 19th day 15 1sof September, 1882.

The eumbination, with the fixed axle H, of HENRY G. YATES. [L 5.] a ear-wheel composed of the flanged and re \Vitnesses: (:essed tire A, the flanged hub-disks D D, CO11 W'ILMER BRADFORD, IO strueted as described. and forming with the CHAS. E. KELLY.
